Morgan Hayes, from the Whitland area of Carmarthenshire, was first diagnosed with neuroblastoma in February 2015, aged just 4.

Morgan underwent surgery, chemotherapy, radiotherapy and immunotherapy during his brave fight against the disease. Despite being given the all-clear at one point following a clinical trial at Bristol Children’s Hospital, the cancer returned.

A campaign - Morgan’s Fight - was set up by Morgan’s parents Ben and Sophie and thousands of pounds was raised in order to try to get life-prolonging treatment in the United States.

However, Morgan’s condition had progressed and he was unable to go ahead with treatment in New York, and instead continued to receive radiotherapy at home in the UK.

His death was announced on Friday afternoon, following his passing on Friday morning.

A statement on the Morgan’s Fight Facebook page said: “It is with a very heavy heart I write this on behalf of Ben, Sophie and their families.

“Morgan passed away peacefully in his sleep this morning, in the arms of his Mum, Dad and family.

“We thank you all for your on going support and kind words.

“Please respect the family’s need to grieve together during this very difficult time.”
